7.15.2 PID inching

After setting the PID control parameters, inching is possible by following means:

Control the overshoot

Shorten the derivation time and prolong the integration time when overshoot occurs.

Achieve the stable state as soon as possible

Shorten the integration time (Ti) and prolong the derivation time (Td) even the overshoot occurs,
but the control should be stable as soon as possible.

Control long vibration

If the vibration periods are longer than the set value of integration time (Ti), it is necessary to
prolong the integration time (Ti) to control the vibration for the strong integration.
Control short vibration
Short vibration period and the same set value with the derivation time (Td) mean that the derivation
time is strong. Shortening the derivation time (Td) can control the vibration. When setting the
derivation time as 0.00(ire no derivation control) is useless to control the vibration, decrease the
gain.
